As I browsed through the trees yesterday it occurred to me, sometimes there is a lack of local advice and/or the local advice is not the best.
For example, most of the avocado varieties pushed by the local nursery haven't fruited for me. As well as some Florida varieties. The varieties that the local nursery advised won't do well are actually doing the best. For example, I was told Hass doesn't do well here, but it's been easily the most prolific of all (with 4x more fruit than the next closest variety). Other notes Lamb Hass, Holiday, and Ota have also done quite well. Holiday is pushed locally.
If I was to do it again (on a larger scale), I would set up a test area planting at 7x7 ft spacing and find what fruits/when over a period of 5 years, then plant that variety out or top work an existing field. Or plant out a variety of trees and just plan to just top work the entire field.
